This data is collected for the State’s public roadway inventory to meet Federal reporting requirements for the Highway Performance Monitoring System (HPMS). Fields describe roadway segments identified by beginning and ending measured points, plus fields that store various data related to curves. Collection MethodTo measure horizontal curvature, Fugro Roadware utilizes high accuracy Trimble GPS (+/- 2 feet) and the Applanix POS LV System.Newest Record in Dataset2018Oldest Record in Dataset2016Data Collection InstrumentNot specifiedField Names, comma delimitedroute, refpt, endrefpt, runlength_from, runlength_to, seg_length, curve_updateyr, pricurve, pricurveclass, seccurve, seccurveclass, grade_updateyr, prigrade, prigradeclass, secgrade, secgradeclass, objectidDate of Initial Dataset Creation2016 for curve data, 2018 for grade data
